A ".t'uithei object oi rthe invention, is to mixing;l boitl to aline with 'the bed oi the Feuidiinier machine.

A still'turther object is to pkoi/ide .means for regulating the How ei papeiv stock through the mixing bok.

n the accompanying di'awings,-i 1gure l, is a side iiew .oi' suiiicient oi a mining bon andthe Foiudi'inier machine to illustrate .my invention; Fig. 2, is a longitudinal see-- tional View of the machine; 'iig. is a transverseI- sectionai View on' the hne 3 5, `=Fig. i., o" ene-haltet" the Fomdriniei ma `,ehi.ne; lfig.f ei, is a perspective View of thev `mining boX,and Fig. is a View off a detaii' fof Fig. 3.

machina y f B is the fra-me oi the Fonrdifijniei ma- ',teiiine, having upper and knveiv longitudinal members b and b2. This Fonidrinieima:-

le me,1 in the present instance, is suspended by 'straps b hung from vertically adjnsteble is a nut one end screws C adapted to bearings c on the mit@ ing boi; .fi. .iheie is one of these seiews at each side of the machine and on each seifew Each nut isin the form oi a wenn Wheel andmeshing-With the Wheeis aire Worms e on the tiensveise shaft E; on of the shaft is a hand wheel e by which it is turned. On turning the Wheei. e the :trame B of the Fonidfinier machine can be raised or lowered.

fi is the screen on which the paper is made. This screen passes around. a ini. t" mounted on the shaft l at the inlet end, o the nia- .chine and around the tisnai ioiis at the op" pesite end oithe machine.`

The mixing chamber oi the linking bei: n. is dividediiite twesections e, a', by a vertically adjustable partition F forming a gate valve controlling the HOW of material to the Fourdrinier' machine. This Valve is connected by a link f to the arm f of a rock shaft VF mounted inbeaiings on the frame of the mixing box. @n this rock shai'tis a hand lever F2 provided. with a pawl f2,

eov

which engages,the teeth ofla segment f3 n the side oi the mixing box. This p awl is so arranged and the teeth are so for-med thatthe gate F can be, locked in its closed posi` tion, es illustrated in Fig. 2, or in its raised posit-ion, when it is desired to allow "stock to pass 'from one poiton ofthe compartment to the othei;,.Y

0n the iowei' edge of the gate F is a rubbei strip ft which makes a tight seal between the bottom of the box and the gate.

Adapted to siide on the face of the box A is eweii G having a.4 hQriZontal section g eX- -tending to a, point close to the screen roll i.

Secured to this Weir is a cloth H which exf tends vover the edg'ge of the screen and pre- `vente Watei" flowing down between the screen and the edge of the weiif. `Blocks-ig are 1oing ,and adjustableplates Kf-K are secured to the transverse strip Gr of the Weir and the flanges 71, oi" the oloth-H are secured to these plates, so thattheife 1s no leakage at either side of the wenn cated on the Weir G on each side of the open A iubber gasket J is secured to the face L2 of the box A. extending -under theope'ib ing and on each side thei'eof, so as to prevent leakage between the box andthe Weir G. The Weir is connected to the head C of the screws C by adjustable rods nf-n, Fig.

5, so that it moves with the end of the Fourdriniei machine when it is adjusted, thus'insui'ing the proper reiation between the outlet oi the mixing box and the upper surface of the screen.

@n each end of the Wei),1 G 'are brackets g2 and extending from one bracket to the other is a birace rod g3. The rods n extend through openings in the brackets vand,

thongh openings in lugs n on the heads C', Fig. 5,-the :rods are' threaded and nuts are mounted en the mds so that the Weil' can 'be ediusted vertically independent 0f the screws C if desired.

The operation is'ae follows-The pape" pulp is -aignedinto the .mixing box from the receivin ehawhei A.

,D in the oidi'naiy inannei' and the vaive F is reisde byoperating the lever' F2 to the required height to allow the pulp to ow under the valve, when the pulp reaches the weir and over the screen of the Fourdrinier section of the machine. When it is desired to raise the end of the Fourdrinier section, all that is necessary is to turn the hand wheel c which turns the nuts c on the screws C and when the Fourdrinicr frame is raised theweir G is raised with it, increasing the height'of the pulp in the section a of the mixing box and allowing a further 'How of the 'pulp over the making wire of the Fomrdrinier machine.

By the above construction the end of the Fourdrinier machine can be raised a considerable distance or lowered. so as to be level or below the level, if desired.

I claim l. The combination in a paper making machine, of a'mixing box, a Fourdrinier frame, a vertically adjustable weir at the discharge end of the box, and means for simultaneously raising the weir and the end of the Fourdrinier machine.

2. The combination in a paper making machine, of a mixing box having a vertically adjustable Weir at the discharge end, a Fourdrinier machine, screws, means for flexibly suspending the Fourdrinier machine from lthe screws, said screws being attached to the weir of the mixing box, bearings for the screws, nuts mounted on the screws, and means for turning the nuts to raise and 'lower the Weir and theFourdrinier frame.`

3. The combination in a paper making machine, of a mixing box, a vertically adjustable Weir at the dischargeA end of the box, a Fourdrinier frame, a making screen on the Fourdrinier frame, and a cloth secured to the Weir and extending 'over the said makintr screen, with means foi-.simultaneously adjusting the frame and Weir.

4. The combination in a paper making machine, offaqmixingbox, a gate valve mounted inthe box, a vertically adjustable 'Weir 'mountedfatfthe discharge end of the box, a` Fourdrinier machine located adja- 'mixing box,

cent to the said Weir, a making screen mounted on the frame, adjusting mechanism at each side of the machine, flexible straps connecting the said mechanism with the frame, rods connecting the weir with the mechanism, and .means for adjusting thel gate of the mixing box.

5. The combinatign in a paper making machine, of a mixing box, a vertically ar- `ranged gate valve located in the box and dividing said lbox into two compartments, a rock shaft, arms on the rock shaft connected to the gate valve, an operating arm secured to the rock shaft, a double pawl pivoted to the arm, and a toothed segment'on the arm of the mixing box' arranged to be engaged by the other end of the pawl.V

G. The combination in a pa er making machine, Voi a mixing box, a ourdrinier frame, a Weir for the mixing box, screws for adjusting the frame and weil' simultaneously, and means for independently adjusting the weir. y

7. The combination in Ya paper making machine, of a mixing box, a Weir therefor, a .Fourdrinier frame mounted" in the front of the mixingbox, screws Afor adjusting the frame, 'adjustable rods connecting the weil' with the screws, and means for raising and lowering the screws.

8. The combination. in a paper making machine, of a mixing box having a discharge opening, a Fourdrinier frame adjacent t e,

a Weir mounted to rest against` the front wall of the `box and carried by the said frame, means for vertically adjusting the weir, and a gasket on eachside and below the opening in the box forming a water tight joint between the weir and the box. lIn testimonywhereof, I have signed my name to this specification, in the presen@ of two subscribing witnesses. l
